3D Camera: RGBD Image Algorithms for Dual-camera Mobile Phone, Lenovo VIBE S1.
- Image Refocus
- Developed an image refocus algorithm which utilizes the depth information to blur the image to simulate an
effect of “large aperture, shallow depth of field”.
- Developed efficient algorithms and applied parallel computing (OpenCL) to achieve real-time interaction.
- Image Matting
- Co-developed an automatic selfie image matting algorithm. Over-segmentation, region-wise matting and
parallel processing are involved to save memory and speed up the program.
